In general, the more we can constrain the range of expected answers, the more accurate recognition will be.
Accuracy will be very good when we can ask questions like:
- What time do you want to arrive ?
- Are you a vegetarian ?
We pretty much know
what to expect a caller to say in answer to these.
Recognisers have a harder time dealing with answers to questions to which a caller could say pretty much anything such as:
- What do you want to do today ?
- How are you feeling ?
Part of our art, is crafting prompts for maximum accuracy whilst retaining flexibility and the user experience.
